The Sonzera 20 is a moderately powered 20-watt combo amplifier with two independently controlled, footswitchable channels designed for maximum versatility. The clean channel delivers full, 3D tones reminiscent of American mid-1960’s amplifiers. The gain channel is related to the clean channel circuit-wise, so that it can be set up to act as a boosted clean channel or manipulated to make the channels sound like two completely different amps (the gain channel can be set from slight to very heavy distortion by simply using the drive and level controls). The bright switch on the gain channel has been carefully tailored to deliver familiar high-end snap and is particularly effective on the low strings, neck pickup settings, and with singlecoils, while the low-end response of the gain channel is full, tight, and clear.
